INDIANAPOLIS -- Sunday is the biggest day here at the NFL Scouting Combine. Media availability continues, while the skill-position players hit the field. Here's what we learned:

» Don't call him "Honey Badger" anymore. Tyrann Mathieu is looking to shed his past. In a fascinating session with reporters, Mathieu talked about rehab, being humiliated and enjoying too many things other than football.

"My best friend right now is honesty," Mathieu said.

Mathieu is short and not particularly fast. But NFL Network draft analyst Mike Mayock still believes Mathieu should find a home in the NFL as a slot cornerback.

» Three players -- West Virginia wide receiver Tavon Austin, Texas wide receiver Marquise Goodwin and Auburn running back Onterio McCalebb -- took aim at Chris Johnson's official 40 record Sunday. Goodwin wound up with a time of 4.27 seconds officially; Austin and McCalebb wound up seeing their unofficial times get downgraded to 4.34. Austin is a matchup nightmare who could sneak into the first round.

» Alabama cornerback Dee Milliner will need shoulder surgery after the combine. He will perform his drills other than the bench press.

» The more I hear, the less I expect Sean Smith to return to Miami. My strong feeling is the Dolphins will use their franchise tag on defensive tackle Randy Starks.

That's a wrap from the media room at the combine, but we're not done in Indianapolis just yet. I'll be writing and chatting on NFL.com/live from the field over the next two days. If I'm going to stay away from my wife and daughter this long, watching is the least you can do.
